Produktnavn: ASTM A513 Type5 Mechanical Grade , DOM Round Steel Tube
Størrelse(Mm): O. D.: 10.0-168.0 W. T.: 1.0-10.0mm L: Max 12000mm

DOM Steel Tubing, is a welded mechanical round steel tube with the internal weld seam removed creating a smooth internal surface. DOM round steel tube has been drawn over a mandrel to produce a tube having more exact dimensional accuracy and tolerances, and a very smooth insde and outside finish. DOM steel tubing is ideal for more stressful applications requiring higher quality, increased mechanical porperties, uniformity, strength, and soundness.

Specifikationer: ASTM A513 type 5, 1020, 1045, 4130 mechanical grade

Programmer: race car frames, roll cages, motorcycle frames,spindles, rollers, shafts, engine mounts, bushings, cylinders, telescoping, osv.

Workability: Easy to weld, cut, form and machine.

ASTM A513 Type 5 Round Steel Tube – DOM Characteristics

ASTM A513 Type 5 Round Steel Tube – DOM is a Drawn Over Mandrel (DOM) tubing product which has closer OD/ID/Wall Tolerances than ERW products. Produced from 1020 og 1026 stål.

DOM Round Steel Tube, is a welded mechanical round steel tube with the internal weld seam removed creating a smooth internal surface.DOM is actually not a type of tubing, but a process that is applied to tubing after it is initially constructed. It is Drawn Over a Mandrel…which “cold works” it, giving it more exact dimensions relative to the inside and outside diameters, a smoother finish, and better alignment of the crystal lattice structure.

Although it is almost always referred to as a SEAMLESS tube, technically it is NOT seamless tubing, and it started life as some sort of EW (electric welded) tubing. During the manufacturing process, the weld line becomes nearly undetectable, thus it is referred to as SEAMLESS. It is considered a high strength, high quality tube, and is normally constructed from SAE 1020 eller 1026 steel ASTM A513,Type 5.

DOM round steel tube produce a tube having more exact dimensional accuracy and tolerances, and a very smooth inside and outside finish. DOM round steel tube is ideal for more stressful applications requiring higher quality, increased mechanical properties, uniformity, strength, and soundness DOM is commonly used in the manufacturing of race cars and motorcycle frames.

1020 is normally used in the manufacturing of small-diameter or thin-wall DOM steel tube. 1026 grade is normally used in the manufacturing of DOM over 2″ OD, with walls heavier than .156″.
